As climate risks loom larger in the corporate world — threatening the long-term viability of certain supply chains and product lines, not to mention reputation — how can corporate boards of director’s gauge and respond to them more thoughtfully and effectively?

In a situation directly tied to climate change risk, Exxon Mobil added an atmospheric scientist to its board in January after shareholders pursued a resolution to appoint more board directors knowledgeable about climate issues.

Meanwhile, BlackRock Inc., the world’s largest asset manager overseeing $5.1 trillion, told portfolio companies in the energy and real estate sectors that it expects a company’s “board to have demonstrable fluency in how climate risk affects the business” if the organization wants BlackRock’s continued investment.
